Chinese Virtual Observatory
(China-VO)
• Advanced research platform for
Chinese astronomers
• Acquire data and technologies
from IVOA partners
• Share our data (LAMOST, SST,
FAST, BATC …) with
international astronomers
• Bring up a group of VO-oriented
astronomers, engineers and
students
• Education outreach
